Kidneys do chhote, lekin bahut hi zaroori organs hain jo peeth ke neeche, dono taraf, reedh ki haddi ke pass hote hain. Inka mukhya kaam sharir se gande padarth aur extra paani ko nikalna hota hai. Har din, kidneys lagbhag 150 liters blood ko filter karte hain aur jo padarth sharir ke liye harmful hote hain, unhe urine ke roop mein bahar nikalte hain. Is prakriya ke zariye sharir saf aur swasth rehta hai.
Kidneys ka sabse bada kaam blood ko filter karna hai. Blood filter hone ke baad jo waste products hote hain, jaise urea aur toxins, unhe urine ke roop mein nikal diya jata hai. Yeh urine phir bladder mein store hoti hai aur jab bladder full ho jata hai, to urine sharir se bahar nikalti hai. Is prakriya ke zariye sharir ke andar ke waste aur gande padarth nikal jate hain.
Iske alawa, kidneys sharir mein pani aur namak ka balance banaye rakhte hain. Jab sharir mein zyada paani hota hai, to kidneys usse urine ke zariye bahar nikal deti hain. Agar sharir mein pani ki kami hoti hai, to kidneys paani ko bachane ki koshish karti hain. Yeh balance sharir ke liye bahut zaroori hai kyunki yeh blood pressure ko control mein rakhta hai. Blood pressure ko theek rakhne ke liye kidneys angiotensin naam ka ek hormone bhi banati hain, jo blood vessels ko tight ya relax karta hai.
Kidneys ke aur bhi kaam hote hain. Yeh kuch zaroori hormones banati hain, jaise erythropoietin, jo bone marrow ko naye red blood cells banane ke liye signal karta hai. Red blood cells sharir ke har hissa tak oxygen pahuchane ke liye zaroori hote hain. Agar kidneys yeh hormone nahi banati, to sharir mein oxygen ki kami ho sakti hai, jo thakan aur kamjori ka karan ban sakti hai.
Kidneys vitamin D ko bhi active form mein convert karti hain, jo haddiyon ke liye zaroori hota hai. Yeh vitamin calcium ko absorb karne mein madad karta hai, jo haddiyon ko majboot banane ke liye zaroori hai. Isliye kidneys sirf sharir se waste nikalne ka kaam nahi karti, balki overall health ke liye bhi zaroori hain.
Agar kidneys theek se kaam na karen, to sharir mein gande padarth jama hone lagte hain, jo serious health problems ka karan ban sakte hain. Isliye kidneys ka dhyan rakhna aur healthy lifestyle follow karna bahut zaroori hai.
